Description

Technical Field

[0001] The utility model relates to the technical field of infrared spectrometers, in particular to a Fourier transform infrared spectrometer. Background Art

[0002] Fourier transform infrared spectrometer, referred to as Fourier infrared spectrometer. It is different from the principle of dispersive infrared spectroscopy. It is an infrared spectrometer developed based on the principle of Fourier transform of the infrared spectrometer after interference. It is mainly composed of infrared spectrometer source, aperture, interferometer (beam splitter, moving mirror, fixed mirror), sample chamber, detector and various infrared reflectors, lasers, control circuit boards and power supplies. When using the Fourier transform infrared spectrometer, vibration should be avoided as much as possible to ensure the stability of the equipment. However, the existing Fourier transform infrared spectrometer does not have the ability to resist vibration. When the platform shakes or vibrates and causes the infrared spectrometer to vibrate, it will affect the test results and cause large test errors. Therefore, we propose a Fourier transform infrared spectrometer. Utility Model Content
